A42MX09-VQ100M

Overview

The A42MX09-VQ100M is a field-programmable gate array (FPGA) from the Microchip MX series, manufactured by Actel. It features 336 logic elements and approximately 14,000 system gates within a 100-pin VQFP package. The device supports mixed-voltage operation with core and I/O supplies of 3.3V or 5V, operating between 4.5V and 5.5V. It offers 83 user-programmable I/O pins and functions at a maximum clock frequency of 70.2 MHz. The component operates within an extended temperature range of -55°C to +125°C and includes up to 2.5 kbits of configurable dual-port SRAM.

Feature Summary

• Single-chip ASIC alternative capability with high resource utilization and deterministic timing.
• Mixed-voltage operation supporting both 3.3V and 5.0V core and I/O supplies with PCI-compliant interfaces.
• HiRel features including radiation tolerance options and availability in military-grade ceramic packages.

Applications

• Aerospace and defense systems requiring radiation-hardened logic solutions.
• Industrial control applications needing mixed-voltage interface compatibility.
• Automotive electronics operating under extreme temperature conditions.

Procurement Notes

Verify the specific suffix 'VQ100M' against official Microchip documentation, as standard listings often use 'VQG100M'. Confirm current production status, as some MX series variants face end-of-life notifications. Check for export restrictions related to HiRel capabilities. Ensure compliance with RoHS and REACH regulations for your region. Validate moisture sensitivity level handling requirements upon receipt.

Selection Notes

Select this model for designs requiring non-volatile flash-based FPGA technology with low power consumption. Compare logic density against the A42MX16 if more resources are needed. Consider package constraints when choosing between VQFP and PQFP variants. Verify voltage levels match target I/O standards before finalizing the part number.

Part Context

This component belongs to the Actel MX family, now part of Microchip Technology. The series is known for flash-based FPGA architecture, eliminating the need for external configuration memory. It serves as a drop-in replacement for complex PLDs and small ASICs in legacy and new designs.

Replacement Considerations

Direct pin-compatible substitutes include other MX series devices like the A42MX08 or A42MX16, depending on logic density needs. Verify that any replacement maintains the same voltage and temperature specifications. Cross-reference datasheets for timing differences.
